I just have a couple questions. So this month i was like 4 days early for my period it started off really light for two days and then started to get heavier but it wasnt my normal period. so it was just spotting for the first two days, and it just doesnt feel right. Me and my boyfriend had unprotected sex about three times after my last period. What is really weird is that my boobs dont hurt at all like they normally would during my period, but my nipples are highly, highly sensitive.

Could I be pregnant?
I havent tooken any tests, but if you guys think i should then i will.
Thank you
